The machine is constructed with the usual frame comprising the bed-plate1 and overhanging bracket-arm 2 in which latter is journaled themain-shaft 3 operatively connected at its forward end with therectilinearly reciprocating needle-bar 4 carrying the needle 5cooperating with which in the production of stitches is the shuttle 6mounted in the race 7 beneath the bed-plate and actuated by means of therock-shaft 8 operatively connected with the. rearward portion of themain-shaft.

The longitudinally reciprocating and laterally swinging work-blampcarrying slide-bar 9 has depending from its rearward end a slide-block10 moving in the usual guide-slot of the bed-plate 1 and pivIOtallysecured to said slide-bar by means of a fulcrum-stud 11 (indicatedpartially in Fig. 3). The slide-bar 9 receives its longitudinalmovements through 'a rigid post 12 having adjustably secured thereon bymeans' of the set-screw 13 a contact block 14 fitted within thedependingslotted arm 15 of a rock-lever having a fixed fulcrum at 16 andprovided with an upwardly extending arm 17 carrying a roller-stud 18entering the cam-groove 19 in the forward face of the rotary camwheel 20mounted upon the fixed fulcrumstud 21 and having a worm-wheel 22 meshingwith the worm 23 upon the main-shaft 3. The rearward face of thecam-wheel is formed with a cam-groove 24 entered by the stud 25carried-by the upper arm 26 of a rock-lever having a fixed fulcrum at 27and having a'lower arm 28 adjustably connected by means of the sectionallink 29 with a rearwardly extending arm 30 of an elbow-lever whoseforwardly extending arm 31 has a transverse link connection 32 with theusual stud depending from the forward portion of the slide-bar 9,whereby lateral swinging -movements are imparted to the slide-bar.

The cam-grooves 19 and 24 are suitably shaped for. cofiperation inimparting to the forward end of the slide-bar 9 ste -by-step feedingmovementsin arectangu ar path,

the adjustments of the connecting trains ofmechanism serving todetermine the lengths of travel of the work-clamp"longitudinally andlaterally of the bed-plate.

Secured upon the forward end of the slide-bar 9,by means of the bolt33an'd steady pins 34 is the lower work-clamp plate 35 having its upperface roughened orserrated to form the lower java of the primaryworkclamp, and overlying the same is the serrated lower face of theupper primary clamp member 36 in the form of a hollow rectangle, suchmember having (as indicated in Fig. 3) a rearwardly o fi'set lug groovedupon its under side to receive, and secured by means of a screw 38 upon,the forwardly projecting portion 39 of the slide-bar 40 which isjournaled in a suitable guideway in the head 41 of the goose-neck frame42 of the attachment which is rigidly secured by means of fasteningscrews 43 upon the slidebar 9. The rectangular needle-aperture of theclamp member 36 affords a label cavity in which is introduced alabel-receiving shell having side-walls 44 fitted to those of the labelcavityon three sides and having at the bottom an inwardlyextendingnarrow lip 45 of rectangular formto afford a label-supportingseat, such shell having along its upper edges the outwardl extendingflanges 46 with screw-apertures 4 entered by screws 48 for securing themupon the top of the member 36. Loosely fitted to the side walls of thelabel cavity is the rectangular labelclamping foot 49 whose lowerserrated edges afford the upper clamping jaws for the margin 'of thelabel, such foot being provided with a rearwardly extending lug 50ribbed upon its under side and provided with an aperture 51 to receivethe fastening screw 52 their guideways.v Each of the slide-bars 40 and54 is notched in its upper end to receive the forward end of one of thespring wires 57 whose down-turned ends 58 enter suitable apertures in alug 59 upon the attachment frame42, while the intermediate portions ofsuch springs are pressed downwardly by engagement with the points ofadjusting screws 60 extending through thelug 61 upon the attachmentframe and se-' cured against turning by means of the jamnuts' 62.

The upper work-clamp member 36 has a forwardly and upwardly extendingportion 36* formed with a segmental slideway, of rectangular'cros's-section'but open at the top and provided with overhanging plates63' secured thereon upon opposite sides of such slideway by means offastening screws. 64 and having depending guard-lips 65 spaced inwardlyfrom the walls of said slideway.- Within said slideway is fitted asegmental channel-shaped member .66 having a central rib 67, andaffording a guidechannel to receive the tape to be fed into the labelcavity in register therewith and formthe bottom a-sharp edge of archedform ing a continuation thereof. The end of the member 66 is cut ofi'transversely to form at serving as a ledger blade in conjunction with amovable knife-.bladein severing short lengths from the tape to form thelabels to be attached to the body fabric. Upon the outer end portion ofthe tape-guiding member 66 is adjustably secured by means of screws 68 aplate 69 provided with a hook 70 to which is attached one end of aspring 71 whose opposite epd embraces a hook 72 upon a plate 73adjustably secured by means of screws74: upon the adjacent end of theclamp member extension 36*, whereby the tape-guiding member 66 isnormally pressed toward the label cavity. Upon the end of the labelclamping foot 49 is secured by means of screws 7 5 the transverseknifeblade 76 whose sharpened lower edge cooperates with theledger-blade 66 at the adjacent end of the tape-guiding member 66 insevering the tape as said foot is lowered into operative position. i

Tapped into the forward face of the slidebar 40 concentrically with theguiding channel of the tape-guiding member 66 is a shouldered stud-screw77 upon which is fulcrumed the hub 78 of the swinging arm or lever 79which is formed with a radial socket 80 having fitted therein the head81 of a plunger with reduced stem 82 passing 1 through the inner end ofthe socket and terminating in the head 83. A spring 8% surrounding thestem 82 is interposed between the plunger-head 81 and the end of thesocket 80 for forcing the plunger-head toward the guide-member 66, andthe plunger-head' is provided with a bifurcated tapefeeding foot or claw85 serrated upon its operative edges. The plunger head is provided witha lateral wing 86 passing through a slot 87 in the wall of the socket 80with its outer edge adapted for engagement by the hooked member 88. of apawllever 89 pivotally mounted upon a screw-stud 90 upon the swingingarm 7 9. The pawl-lever 89 is provided with a laterall extending lug 91between which and the bottom of a socket formed in the arm 79 isinterposed a spring 92 for normally pressin the nose of the hook 88toward the wing 86 of the plunger, and the lever 89 is provided with arearwardly extending arm 93 ada ted for engagement with the cam-plate 94disposed at the adjacent side of the extension 36 of the clamp member 36bv means of a fastening.

screw '95 extending through the angularly disposed foot-piece 96 of saidcam-plate. The plunger-head is also provided upon its rearward; sidewith a stud 97 passing through a slot 98 in the socket and carrying aroller 99 adapted in the advance position of the carrving arm 79 to moveup the camshaped upper edge 100 of the cam-block 101 adjustably securedto the side of the clamp member extension 36 by means of a screw 102entering a slot 103 in such block; and said roller is also adapted toride down the cam-shapedfedge 104: of the cam-block 105 whichis alsoadjustably secured upon the side of the clamp member extension 36 bymeans of screws 106 entering suitable slots in said block.

Secured to the lu 37 of the clam member 36 by means of the fasteningscrew 107 is a bracket-piece 108 carrying a segmental guide-rod 109overlying but spaced slightly above the rib 66 ofthe tape-guidingchannel member 66, tape-smoothing wings 110 and 111 being providedat theopposite extremities of the rod 109 and conforming in their lower oroperative faces with but spaced above the bottom of the tape channel soas to insure the entrance and delivery of the tape in arched form to andfrom the tapeguiding channel. The rod 109 is shown formed with upturnedend 109 to facilitate the introduction of the tape in the space betweenthe same and the rib 66 of the chan nel. The object of arching thebottom of the channel is to arch the label so as to stiflen it forfeeding and also to provide a corresponding form for the edge "of theledgerblade at the entrance to the label cavity so as to insure a drawout between the ledgerblade and the straight operative edge of themovable knife-blade 7 6.

The carrying arm 79 forthe tape-feeding foot has extending forwardlyfrom its hub an arm 112 provided with a slot 113 in radial relation withthe fulcrum-stud 77, which slot is entered by a roller 114 carried by astud 115 tapped into a lateral extension 55* of the face-plate 55 andsecured therein by a jam-nut 116. As will be observed, the lift ing ofthe slide-bar d0 carries the fulcrumstud 77 upwardly, and the engagementof the slotted member 112 of the feed-arm 79 causes the advance of thelatter toward the label cavity, while the lowering of the slidebarproduces a reciprocal motion of the arm 79.

As shown in Figs. 1 and 2, the machine is provided with clamp-liftingmeans comprising the reciprocating bar 117 1ournaled in the head of thebracket-arm and provided with a fixed collar 118 between which and theupper bearing member is interposed the spring 119 for normally pressingthe bar downwardly. The reduced lower end of this lifting bar has fixedthereon by means ofthe screw 120 the boss 121 of a rigid angular arm 122whose operative portion extends parallel with and adjacent theface-plate 55 of the attachment frame and beneath forwardly extendingstuds 123 and 124 tapped into lateral ears 125 and 126 of theclampoperating slide-rods 40 and 5%, such studs passing through slots'127 in the face-plate 55. The lifting bar 117 has fixed upon its upperend portion a collar 128 beneath which extends the forked forward end129 of the rock-lever 130 fulcrumed at 131 upon the bearing bracket 132and having inthe extremity of its rearwardly extending arm the aperture133 'for attachment of the treadle rod or other usual connection toactuating means beneath the machine base.

lln the normal positions of the parts, the pressure members 36 and 49are maintained in their lower or operative positions under the action ofthe springs 57, the tape-feeder carrying arm 7 9 being in its upper orretracted'position, in which the lateral arm 93 0f the pawl-lever 89 isin engagement with thecam-plate 94 so as to disengage the hook 88 ofsuch lever from the wing 86 of the plunger 81, while the roller-stud 97of said plunger rests upon the upper operative edge of the cam-block 105for maintaining the tape-feeding foot 85 lifted above the bottom of thetape-channel in opposition to the spring 84.

Preparatory to the operation of the machine, the end of the tape, whichmay be wound upon a spool supported upon the head of the brackevarm in awell-known manner, is introduced into the tape-guiding channel beneaththe guide-rod 109 to the forward end of the member 66 and abuttedagainst the flat face of the lmife-blade 76. The actuation of therock-lever 130' to raise the lifting arm 122 serves to engagesuccessively the pins 124 and 123 of the slide-bars 54- and 40 so as tofirst partially lift the label-clamping member 49 to admit the tape andthen impart the requisite lifting movement to the work-clamp member 36.As the slide-bar 40 rises, it carries upwardly the fulcrum-stud 77 andthe arm 79 advances toward the label cavity, which causes theroller-stud 97 to move down the inclined edge'of the cam-block 105 soas'to engage and advance the label strip or tape until the cam-rollerrides up the inclined operative edge 100 of the cam-block 101, when thefeeding foot-85 becomes disengaged from the surface of the tapeejust asits forward extremity reaches the end wall of the label cavity, As theplunger 81 is forced upwardly, the nose of the pawl 88 snaps beneath theguide-wing 86 and thus locks the feeding foot in raised or retractedposition. The release of the rock-lever 130 now permits the lifting arm122 to descend so as to first seat the work-clamp member 36 firmly uponthe body fabric previously introduced between the same and-theclamp-plate 35, after which the label clamp member 49 descends upon theportion of the tape lying within the latter, and in so doing carries theknife-blade 76 downwardly in contact with the ledger-blade 66 wherebythe section of tape within the label cavity is severed from the body ofthe tape and securely clamped around its edges upon the seat thereforafforded above the body fabric by the inwardly extending lips 45 of thehold.-

ing member 44. The efiective coiiperative relation between the blades 76and 66 is insured by the action of the spring 71 which forces theledger-blade yieldingly in contact with the reciprocating blade. In theretrograde movement of the feeder-carrying arm 79 under the descendingmovement of the slide-bar 40, the engagement of the pawllever 89 withthe guide-wing 86 of the plunger 81 maintains the feeding foot 85 liftedabove the tape, so that the return of this member to initial positionhas no effect upon the tape. As the swinging arm nears its initialposition, the member 93 of the pawl.

lever 89 again engages the cam-plate 94 whereby the nose 88 of thepawl-lever is disengaged from the wing 86, but the descent of thefeeding foot into operative relation with the work is prevented by theengagement of the roller-stud 97 with the upper portion of the cam-block105. 3

While the embodiment-of the present improvement shown and describedherein is deemed preferable, it is to be understood that the details ofconstruction and arrangement of its various parts may be modified to aconsiderable degree without departure from the scope of the presentinvention.

llt is evident that the tape-smoothing wings 110 and 111 may, ifdesired, be made in a continuous plate with suitable slots to receivethe bifurcated feeding foot 85, in lieu of the connecting rod 109, andmay be secured in position within the tape-guiding member 66 by anysuitable or convenient means.
